So, Palemoon is just like an old Firefox on Unity DE. It has no integration with globalmenu/LIM, and all.

In the addons page, it got 4 default addons, with unity desktop integration being one of them, but they are all disabled. Enabling them makes no effect.I think it needs some customization, changing target or something, but I don't know which file to edit. Can you help me?

Their location is:/usr/share/xul-ext/ubufox/usr/share/xul-ext/unity/usr/share/xul-ext/websites-integration/usr/lib/xul-ext/webaccounts

First: please update your addons. The <em:(min|max)version> is much below Pale Moon's range (I see 15.* for one of them, another has 18.*). I'd also recommend leaving out ubufox, seems like it tries to do some integration with apt.

No updates found. They're already the latest version.Should I change the version number manually? But Firefox is on version 29, shouldn't it be broken as well for Firefox if the version number is the culprit?

Oh, I see. But I think they don't make any change to Firefox codebase, only patches in add-ons form. That's why maybe we can make it work with Palemoon too.But I could be wrong, and if they do change the codebase itself, then I guess it's a check-mate.

I don't really care about webapps, online account and ubufox.

You can uninstall this if you prefer to use a pristine Firefox install.

Although I can live without them, it feels somewhat weird without unity-integration, without on top-panel and empty HUD.

Edit: Just looking at Synaptic again...

Webapps? If this extension is really about webapp and not the UI, I don't know anymore where they do the change..

I will try it tomorrow, it's getting late here. But is it alright to have two different version of Firefox? I'm still not familiar with how linux system works. Even a single program seems to put its files everywhere across the system.. But I guess it won't replace or conflicting, right?

No, they don't have it in repo Actually, despite the description, I don't see ask.com in search engine. The list are just Google, Yahoo, Bing, Amazon, Duckduckgo, Ebay, Twitter, Wiki.

I just tried it. Firefox 24 ESR gave a same result as Palemoon. But to my surprise, even Firefox 29 also gave a similar result. No global menu, no HUD.I guess Canonical patched Firefox on codebase level then?

Or is it because they build it on non-Unity? Do you think simply rebuild the source will help? I remember compiling other program like Desmume from a tarball giving it global menu immediately..
